Answers (1)
Correct option 2) Melatonin
The 24-hour rhythm of our body, also known as the circadian rhythm, including the sleep-wake cycle, is regulated by the hormone melatonin. Melatonin is synthesized and released by the pineal gland in the brain in response to darkness. It helps to regulate the sleep-wake cycle by promoting sleepiness and maintaining the body's internal clock. Melatonin levels typically increase in the evening and remain elevated throughout the night, promoting sleep, and decrease in the morning, signaling wakefulness.
